lib all wiz om it may concern v lie it ,lnio'wn that we, lsnnonn FRY and Jason SHAKE-s, a citizen of the United States and a subject of the Czar of Russia,

respectively, and residents'of St. Louis, Mis-' sour-i, have invented certain new and useful Improvements in Phonograph Attachments for Player-Pianos, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

Our invention relates to improvements in phonographic attachments for player pianos, and the object of our invention is to operatively combine with the driven mechapointed out in-the claims and illustrated bythe accompanying drawings, in which- Figure l isa front elevation of a player piano, certain parts being removed, showing' the relative arrangement of the player mechanism with a phonograph as contemplated by our invention; Fig. 2 is an enlarged detail plan illustrating the detachable gear connections between the driven music roll of the player piano and a phonograph; Fig. 3 is a front elevation of the.

parts shown in Fig. 2; F ignl is an end view of the parts shown in Figs. 2 and 3; Fig. 5 is a transverse sectional elevation taken on the line 5-5 of Fig. 3; Fig. 6 is a transverse sectional elevation taken on the line 6-6 of Fig. 2; and Fig. 7 is a detail sectional plan illustrating the clutch connection between the player piano mechanism and the phonographic mechanism.

Referring by numerals to the accompanying drawings: 8 designates the piano cas ing and 9 the sound board thereof, both of which are or maybe of any desired construction. v I

10 designates a cabinet in which 1s gournaled a motor driven shaft 11 carrying a spool 12 and a. second shaft 13 carrying a spool 14. Arranged to be wound upon the spools 12 and i l isthe ordinary perforated sheet 15.

anism not shown).

arm '20. link 21 leading to the having a clutch member 30 Connected with the shaft ll-is'the ordi narymotor (not shown and this motor is equipped with the ordinary reversing mech- All player pianos are equipped with such a reversible motorand henceit was not deemed necessary to illustrate it indetail.

l6 designates a shaft which is secured in a position conveniently accessible'to the 0perator'and is equipped with an ordinary lever 17.

18 designates a shaft arranged parallel with the shaft 16 and which carries at its one end an arm 19 and at its other end an Connected with of the motor, previously referred to.

the arm' 20 is a reverslng mechanism Secured'to the sound board 9 is'alframe 22 and rotatably mounted in said frame'is a support 23 for a 'phonographic record of the cylinder type, and located beneath the cylinder support is a feed shaft 2 1-.

I designates a pulley whichis secured to rotate'with the cylinder support '23, and 26 designates a pulley mounted on ashaft 27- in the frame 22. Embracing the two pul-' leys 25 and 26 is a belt 28 forming a direct drive between the shaft 27 and the cylinder support 23.

Secured to the shaft 27 isai pinion 29 carried thereby.

The pinion 29 meshes with'a gear. wheel'31- 5 carried by "the shaft llwvhich driven shaft of the piano player mechanism; It will be obvious from this'gear connection is the motorthat when the music rolls are di'iv'en the a record and support 23 will be driven.

' 32 designates a clutch member which is feathered .to the shaft 27 and 33 designates a lever for the operation of the clutch member 32. By this means they operatoit may disconnect the phonograph from the piano player, if desired. l

In order to secure uniformity of action, we have arranged an ordinary centrifugal governor 3 which is geared to the shaft 27 through the medium of the gear wheels 35. The one end of each leaf carrying the balls of the governor is secured to a sleeve 36, and

connected with the sleeve is a bell crank lever 37 which is held in one position by means of a spring 38 a'nd its one end. impinges an adjustable set screw 39 Through this medium different tensions may be put on the springs on the governor, thereby controlling its speed as desired.

Supported in the frame 22 and paralleling the feed shaft 24 is a shaft 40 which constitutes a support for the frame 41 carrying the sound box 42.

43 designates an arm carried by the frame 41 and arranged. to support the feed nut 44 which coacts with the feed shaft 24 to IHOX'Q- the sound box longitudinally of the phonograph record 45 carried by the support 23. Als shown in Fig. -5, the relative-arrangement between the feed nut 44 and the sound box 42 is such that when the sound box is elevated to free it from the record, the nut 4-4 is elevated above the feed shaft.

Extending parallel with the feed shaft 24 is a rail 46 and fulcrumed to the frame 41 of the sound box is a lever 47. Secured to said lever 47 is a rod 48 connecting with a lever 49 which in turn has secured thereto a link 50 connected with the} arm which controls the motor and its reversing mechanism.

Assuming the phonograph to be connectedto play with the piano and the operator desired to repeat both the music and the record of the phonograph, -the lever 17 is grasped and, through the medium of the shafts 16 and 17 and the link 21, the motor is reversed. At the same time that the music sheet is reversed the rod 50, through the medium of the lever 49 and rod 48, the lever,

, 1. In a phonograpic attachment for player pianos, means for controlling a motor and a rewinding mechanism for the player piano; a phonograph; a gear connection between the phonograph and the' player mechanism; and .means including a connection between the sound box of the phonograph and the means for controlling the motor and the rewinding mechanism whereby, upon a movement of said controlling means which will effect a rewinding, the sound box of the phonograph will be set to its initial :position.

2. In combinatlon with a player piano having means for controlling its motor and rewinding mechanism; a phonograph having a movable sound box; means for connecting and disconnectingv the phonograph with the player piano mechanism; and a connection between said sound box and the means. for controlling the motor and rewinding mechanism. 3. In combination with a player piano, having means for winding and rewinding music rolls and a lever for the control of said winding and rewinding means; a phonograph having a movable sound box; a gear connection between said phonograph and its sound box and said winding and rewinding means; and means including a connection between said sound box and said lever, whereby a moving of the sound box may be accomplished at the time said winding and rewinding means is operated.

In testimony whereof, we have signed our names to this specification, in presence of twosubscribing witnesses.
